Organometallic compounds are chemical substances that contain at least one bond between a carbon atom and a metal. These metals can be transition metals, main group metals, or even metalloids. Organometallics are important in various fields, including catalysis, materials science, and organic synthesis, due to their unique reactivity and ability to facilitate chemical reactions. One common example of an organometallic compound is Grignard reagents, which are used in organic chemistry to form new carbon-carbon bonds. These compounds play a crucial role in the development of pharmaceuticals and other chemical products, making them essential in both industrial and academic research.
